How to identify isochoric process from the problem's wording?
This is popularly known as first law of thermodynamics. The change in the internal energy brings the change in the temperature and vise versa. … We know that, $$ \Delta U = nC_v \Delta T $$ According to first law of thermodynamics, the heat given to the system at constant volume is known as internal energy. ( $\because$ work done ($W$) = 0 at constant …
